The process to remove Telerik during DNN 9.11.0 upgrade should include the following actions

• Install Resource Manager
• Update all Digital Asset Manager modules to be Resource Manager modules
• Uninstall DigitalAssetsManagement (Digital Asset Management)
• Uninstall DotNetNuke.Web.Deprecated (DNN Deprecated Web Controls Library)
• Uninstall DotNetNuke.Website.Deprecated (DNN Deprecated Website Codebehind files)
• Uninstall DotNetNuke.Telerik.Web (DotNetNuke Telerik Web Components)
• Uninstall DNNSecurityHotFix20171 (DNN Security HotFix 2017.1)

I'm scratching my head with this one.
Any ideas on how to go about it @mitchelsellers @valadas @david-poindexter @bdukes ?

The stages of upgrade process are defined by this code in UpdateWizard.aspx.cs:

Essentially, we are dealing with:

• direct database data updates
• installation of new extensions
• page module replacements
• removal of some existing extensions
• search and replace in config files
• removal of files

The only tools we have to get this done are database upgrade scripts and extension manifest files, correct?
So replacing a page module with a different one will have to be a direct database data update?

Maybe we can create a new Extension to take care of this cleanup, and install and run this new extension as part of the upgrade? And then auto-remove the extension if everything went well, or leave it installed for the user to manually retry later in case of failure?
